Using Eclipse IDE for Java Developers 1.5.1.20120920-0737 in Windows 7 Home Premium:

Whenever I type the @ symbol into a Javadoc comment, Eclipse tries to do a Content Assist autocomplete and gives me an error window. The text in the error window is not selectable, which is extremely irritating, so I'll try to retype all of the message:

The 'org.eclipse.jdt.ui.JavadocHTMLCompletionProposalComputer_all' proposal computer from the 'org.eclipse.jdt.ui' plug-in did not complete normally. The extension violated the API contract of the 'computeCompletionProposals()' operation.

To avoid this message, disable the 'org.eclipse.jdt.ui' plug in or disable the 'Java Proposals' category on the content assist preference page

After I close the error window, the Content Assist window displays correctly... I don't want to disable content assist, so I've come here hoping to fix the underlying issue.

I downloaded and installed Eclipse yesterday - I don't recall having the issue yesterday. When I first downloaded the zip, I tried extracting it in my Downloads folder, but you can't extract it very far from the drive root because the folder structure is so long it exceeds the maximum string length and the extraction fails halfway through. I ended up renaming the zip file "aaa" and extracting it into c:\aaa (putting Eclipse in c:\aaa\eclipse). I tested Eclipse in that folder to verify it worked, then moved it to c:\program files\Eclipse\eclipse and have been using it from there.

Again, I don't recall having this problem yesterday, but I was working on partially completed code so I might not have typed out any new Javadoc comments yesterday. I don't know if the problem is related to me running Eclipse and then moving it into a different folder. I reset all the preferences related to Content Assist, which didn't help, and deleted and re-extracted Eclipse, which didn't help. So now I'm stuck.

Thanks for any assistance. I hope someone makes the text in the error window selectable in future versions of Eclipse.

Please open a bug against JDT Text with the .log and the steps.
